Benefits of technology

[0009] Therefore, it is an objective of this invention to provide a container, sufficiently rigid and impervious, to prevent physical damage to stored items and to withstand a negative or positive internal pressure without deformation.
[0014] Another objective is to provide a versatile storage container that can maintain a positive or negative internal pressure to protect sensitive equipment and instruments from adverse atmospheric conditions.

Problems solved by technology

Usually, these containers have a frangible seal that cannot be resealed once it is breached.

Embodiment Construction

[0022] The storage container 10, shown in FIG. 1, is a portable unit that may be made in various sizes. The container may be small enough to be hand carried or larger for transport in vehicles. The container 10 may also be incorporated into vehicles or permanent structures. As shown, the container 10 has handles 18 to facilitate lifting and / or carrying the container from place to place. Larger containers may be mounted on casters or wheels (not shown).

[0023] As shown in FIGS. 1 and 2, the container 10 has an outer front wall 11 and a door 12. The walls and door may be double thickness sealed together. The volume between the inner walls and the outer walls may be filled or evacuated.

[0024] The outer front wall 11 and inner front wall 27 are connected to outer end walls 13 and 14 with inner walls 28, 29, respectively, are connected to outer back wall 15 and inner back wall 30 forming a four sided structure. The front wall, back wall and end walls are connected to the outer bottom wa...

Abstract

A storage container for isolating delicate items from harsh environments has a rigid exterior forming a continuous box with an open mouth. A gasketed door is hinged to the box and is provided with catches cooperating with clasps on the box to compress the gasket and close the open mouth forming a hermetic seal. A one-way valve is mounted on the container to subject the sealed interior to a pressure differential from the atmospheric condition. A pressure gauge is mounted on the container to indicate the pressure differential existing in the container.

Description

FIELD OF THE INVENTION [0001] This invention relates to the field of storage containers, and in particular, to storage containers for protecting of items that can adversely affected by atmospheric conditions or in environments with adverse conditions. BACKGROUND OF THE INVENTION [0002] The environment can be destructive to certain metals and sensitive valuables. By way of example, the air in coastal regions typically has a very high moisture and salt content which is capable of corroding most metals. When dissimilar metals are present, the moisture and salt can even result in electrolysis of the metals. Alternatively, a desert region is known to have very high dust particle content wherein fine particles can result in premature wear of coatings and rotating items such as bearings. Obviously numerous conditions therebetween can lead to similar premature wear of the valuable. It should be noted that such conditions can be compounded by the inclusion of high temperatures and man made p...
